    Remove _POSIX_REGEX_VERSION

    There is no _POSIX_REGEX_VERSION, so don't check for it.

    _REGEX_VERSION has been removed as well[1], so only keep the -1 return

    for backward compatibility.  I found this when trying to make the

    getconf environment variables typo-proof.

            * sysdeps/posix/sysconf.c (__sysconf): Return -1 for

            _SC_REGEX_VERSION.
